What Can I Eat After Teeth Whitening?

Whitening is one of the most popular ways to remove surface stains and fix overall teeth discoloration. It’s proven to be a safe and effective procedure in the dental world.

But whether you’re getting your teeth professionally whitened or opting for an at-home treatment, there are a few crucial post-whitening actions you’ll want to follow to keep those pearly whites… well, white!

After all – You don’t want to waste all the time and money you put into getting your dream teeth by ruining them in the first few hours after your procedure!


It’s important to know that the process of teeth whitening continues after the treatment itself. This means that when you leave the dentist chair (and/or remove your at-home treatment) the whitening agents and chemicals are still working hard on your perfect smile.

And while the treatment is still working its wonders, it’s natural for the teeth to become more porous than normal, making them more susceptible to surface stains and returning discoloration.

For these reasons, you’ll want to avoid certain types of food and drink that may inhibit your teeth whitening – especially in the first 48 hours post-treatment.

What Can’t I Eat After Teeth Whitening?

Did you know that there are certain foods that can actually harm your teeth after whitening? So, yes – It’s advisable to take certain substances out of your diet in the first few days following your treatment. But which ones can potentially stain and or discolour your pearly whites?

Avoid Darkly-Colored Foods

In general, the key is to stray away from foods that are highly pigmented. In other words, avoid food products that contain rich or dark colors. Because your teeth are more porous than usual, they may soak up more pigment than normal.

These dark foods may include (but are not limited to) :

  • Dark Sodas
  • Coffee
  • Dark Sauces (like soy, bbq, etc)
  • Chocolate
  • Red Wine
  • Tomato Juice
  • Red Meats

Believe it or not, even the juice of most fruit can potentially stain your newly whitened teeth! So avoid strawberries, blueberries, oranges and… well, essentially all fruits sans bananas!

Cut Out Acidic Foods

What’s more, after whitening your teeth and gums will tend to be more sensitive than usual. The enamel on your teeth may also be weakened and more affected by certain products.

Therefore it’s also ideal to remove acidic foods from your diet for a few days. This can help eliminate additional pain or gum irritation that may be caused by consuming acidic foods and beverages.

Some acidic food and drinks to avoid include:

  • Coffee
  • Fruit Juices
  • Pickles
  • Citrus

Taking out these types of food can help prevent enamel destruction and/or discomfort.
